Someday, the idea of this having a live action movie would come...
What can you say about it? Who do you think would fit the cast?
(edit) Personally, I think anime should remain as anime.
And 9 years later I say...
Please no. There is no way you can translate this manga stuff into a movie. Dudes discussing each technique while they are fighting... this timing and stuff only works in manga.
I would rather see a TV series. It is possible to do a live action film when it comes to Anime, the right people just need to be involved and not whitewash roles(Dragon Ball,Gits,Death Note,Speed Racer),although that would not be a problem with Claymore
